But the work has caused severe traffic delays, especially at peak times.

Marske resident Graham Johnson contacted the Gazette to say the works had resulted in “traffic chaos” at various times.

He also questioned the need for the works, adding: “Save for a couple of hours on an evening, there are no traffic queues at all on this roundabout, and those queues are very manageable. I cannot see how these traffic measures will improve what was a perfectly functioning roundabout.”

The scheme is funded by the Tees Valley Bus Network Improvement Scheme. Councillor Helen McLuckie, Cabinet member for highways, planning and transport, apologised for the delays but said the externally funded eight-week scheme was on target.

She said: “Traffic surveys indicated that vehicles were experiencing delays getting on to the roundabout from Kirkleatham Lane at peak times. This scheme will alleviate the problem and the council believes the long-term benefits will outweigh the disruption.

“Together with our construction partners, Carillion, the council is doing its best to minimise disruption but unfortunately delays are inevitable.

“Some work is taking place overnight and at weekends, but the primary aim is ensuring the safety of the travelling public and the workforce. We are continually monitoring the situation and will implement improvements as the scheme progresses to further minimise disruption.”
